> considering that it is currently even hard for engineers to grasp a user's requirements.

That's because users don't know exactly what they want. They know it when they see it, but they don't know how to explain it. They expect the engineers to guide them through to their idea.

But as per example above, that could be done by an app - guiding a user from nothing to whatever he wants by interactively experimenting with features.

Think of a REPL with access to a huge number of libraries, which is searchable by voice input.
